I'm going to be re-doing the O2 sensors in my customs exhaust so that I can move back to Toyota O2 sensors instead of the generic versions that I am currently using (thanks to Slee's O2 sensor bung for Toyota's O2 sensor design you no longer have to try to cut out the bung from your old exhaust pipes when building a new exhaust: Slee - Drivetrain - Drive Shafts).
Unfortunately my stock exhaust was long gone before I built my current exhaust so I don't have an original reference (I let a "professional" shop redo it some time ago and then replaced their bad design/execution myself). I want to make sure that I get the placement correct when I weld in the new bungs. My questions (couldn't find either of these in my FSM):

I want to make sure that I get the placement correct when I weld in the new bungs. My questions (couldn't find either of these in my FSM):
- Which sensor goes to which bank of cylinders? I believe that the sensor for cylinders 1-3 goes to the sensor wiring that is near the front fender, clips to the frame, and then joins the main wiring harness under the brake booster. The exhaust for cylinders 4-6 goes to the sensor wiring that runs up above the transmission. Is this correct?
- How are the stock sensors mounted in the pipes? By this I mean position - twelve o'clock (straight up), three o'clock...?
